EMI-based Validation of Cyber-Physical System Development Tool Chain

We are investigating automated Equivalence Modulo Input (EMI)-based testing of commercial cyber-physical system development tool chains (e.g. MATLAB/Simulink). We present following three independant tools in this repository:

Recent News

Our SLEMI paper has been accepted at the prestigious 42th International Conference on Software Engineering (ICSE 2020, CORE: A*, acceptance rate: 20.3%)!

Requirements

MATLAB R2018a with default Simulink toolboxes

Installation

Please use git to properly install all third-party dependencies:

git clone <REPO URL>
cd <REPO>
git submodule update --init
matlab # Opens MATLAB

Hello, World!

Check out tutorials to get started!

Randomly Generated Seed Models

We use the open source SLforge tool to generate valid Simulink models. Although we initially forked from the project, our current version is independant of SLforge and its predecessor CyFuzz
